String conversion number

• string conversion number in Unix

  I'm extremely sorry to post this here. I googled a Unix category for this post here. But could not find one.
  I have a string in Unix. I need to remove characters from the string.

  var=2012/03/26
  I need to remove the special char's('/') from the string. It should be 20120326. 

  I tried expr substr, but did not get the result.
  
  Sorry again to post in the wrong category.

  Try

  newvar=`echo $var|sed 's/[^0-9]//g'`
  

  Who's going to shoot anything that isn't a digital character in the string in the variable ${newvar}.

  Seems you watch a channel that will (eventually) be interpreted as a date, what happens when the string 'date' lack of zeros? It won't be pretty.

• String to number conversion problem

  I have a VI that pulls in data from a device using VISA, and I got it on another computer to work a few weeks back. I had to transfer the VI to a laptop computer to run a few tests, and now I can't make it work. I am unable to put my VI because the laptop on it's is unable to access the network companies, I will do my best to explain it all, I apologize for the inconvenience! My problem is not however with VISA, it's with an exit VISA number conversion chain.

  I have attached a painting drawing of VI to better explain it.

  I use the block series Visa football match in baud rate and all that many good things to the unit and port settings set of device management. Then, a while loop is entered. The loop will run until you press the stop"" button. The next block of visa is the writing block, he asks for a reading of the device. The next block of visa is the first block of reading, he returns playback in the form of "NA-XXX. X' where x are numbers. The next block of visa is the second reading block, this block just echoes back the command sent to the device. Playback of the first visa read block, "NA-XXX. X' is going exponential/fractional chain to digital converter.

  When you perform a run/debug to highlight run, the release of visa reports the correct value, is the value of the device reading - however the string to number converter generates a 0,000, no matter what channel number is. I am at a loss as to what may be wrong because it's the EXACT set up I had to work very well a few weeks ago!

  I'm using Labview 10 on the laptop, the old computer was labview 7. I'm guessing that this is perhaps the rub... I Redid the VI from scratch, although I have not opened the old VI in labview 10.

  Any help would be appreciated. Again, sorry I am unable to attach the VI.

  Would it not have been easier to just post a screenshot? You might also have used the Tool of Capture of Code. (Which reminds me that I need to install it to my previous versions of LabVIEW, as evidenced by the screenshot I took. )

  As to the question: you probably either:

  • employee analysis of chain initially and when you rewrote the VI you used the regular string conversion functions.
  • Wired an offset value in the string to the number function.

  

• Number to String Conversion

  So the question is, which is rounded up my numbers?  Or, more generally, what have I done wrong here?

  The main program this sub.vi works for the needs these numbers as strings, and I think I picked the wrong number to string conversion .vi or missed a configuration somewhere, because the program takes perfectly good number like - 0.340316 and rounded to-0 (zero negative? it's zero, negative).

  The zero negativity hand, the number of decimal string .vi is rounded up my whole numbers.

  The function is supposed to be converted in its entirety. Just go to help > show contextual help and read the description. The desired function is called fractional number of string.

• "Decimal string to Number.vi" bug in LabVIEW 2009 SP1

  The "decimal string to Number.vi' seems to be the conversion of the input data in the type int32 internally even when the input tape in vi data is expanded floating point (no points of constraint).  This is causing me grief.  See attached vi

  This bug is still present in LabVIEW 2010?

  Thank you

  There is no bug. You use the wrong function (see Help) If you want a floating point output. Use Fract/Exp string to a number.

• Sub - VI with the entry as a string og number

  At this small Subvi. I wonder if I could make it more flexible and be able to take the string and number as a value ('value dbl' market) entry.  Is there some sort of variable of variant type that could be used?

  It is possible with the key to write OpenG (varying) _ogtk.vi. But the problem is that when you want to read this back, you need to know what type it is. If you write to a different section of the config file each with a specific type, the TI will work. With this solution, you must use the key to reading OpenG (varying) _ogtk.vi to read and convert the value to LV

  Another way is to use Get Type Information.vi of the Variant Data Type palette. The trick here is to convert double or string before saving it in the config file (wire structure dealing with the output type of the vi and do conversions in the case of type dbl and string). Here, too, you must use a different section, one for dbl for string. Here, you use the standard Read button live file configutaion palette.

• Whole singed to hexadecimal string to number converter

  HI guys...

  I want to convert the number to hex string to number converter but when I connect integer, otherwise it does not change the value (as if you write 'EC78' you should get "-5000", but I get the value in the range of 60 thousand ")...

  Any ideas?

  Hi Eric,.

  clearly, the OP asked for signed integers!

  Use this approach:

• Number in hexadecimal string conversion problem

  Hello

  for a serial communication, I need to send byte-code in an ascii hexadecimal string. When I use the constants and send them by VISA to the COM port it works fine, but if I use converters numbers it doesn't. Can someone show me what I'm doing wrong?

  Since your string indicator is set to hexadecimal display, it seems you want to a hexadecimal string, a single byte/number.

  (You are currently using a hexadecimally format string, composed exclusively of ASCII of the 2 characters/byte "0.F" characters.) This is not what you want!).

  Here is another solution using type conversion:

  

• The decimal string to number Conversion, cutting necessary zeros

  I'm new to the forum, but have been using labview for awhile. Finally found something that really puzzled me, hope I can find someone who is smarter than me! It may be something obvious too, but here goes. The attached vi is the cause of the error. I have a serial number I need to convert a decimal string into a number, I use later the number of "math" so he need as a number. The system always receives a serial number of 6 characters (ie. 123456), but today the system has received a serial number with two leading figures of the scale (ie. 003456) zeros. This compensation of all the bells of alarm stream (sent 4 digits), but the error found that started the 'intelligence' at the beginning of the monitoring program. I would like to know if there is a way to force the zeros in the decimal number in string to not shave off the coast of the 6-digit value above.

  File is located in LabVIEW 2014

  Ideas or comments, thank you!

  The problem is not the string functions.  This is the display format for your digital indicator.  Change the properties on that.

• Conversion number to a hex string

  Hello

  I want to send a command string hex to a device via the serial port. The chain includes a fixed part (address, function, register) and editable part (setpoint). The fixed part is a string constant hexa (0106 0022) the editable part is a number (1000) converted to string hex (03E8). Finally, the two are coding pour get the final string. The problem is that instead get: 0106 0022 03E8, I get: 0106 0022 3033 4538.

  After concatenates two strings, it seems that the second part is turned into ASCI.

  I can't find the solution!

  Thanks for your help.

  Sorry, I saved the vi in a different version.
